"We needed a performer who could sing in this important role," he explained. "[So I] decided to cast someone from a band I already wanted in the movie."

Estella, who was not familiar with the series prior to being cast, now says she thinks she's perfect for the role. "It's been a bit of dream to be in a movie, especially being a messed up rock princess," Estella said in a statement. "How could I say no? I think the VM fans are going to be very happy!"
